1-(3,5-Difluorophenyl)-3-(3,4-dimethylphenyl)propan-1-one CAS 898779-89-0

Description

The occurrence of 1-(3,5-Difluorophenyl)-3-(3,4-dimethylphenyl)propan-1-one is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(3,5-Difluorophenyl)-3-(3,4-dimethylphenyl)propan-1-one (CAS 898779-89-0) is a high-purity analytical reference standard with the molecular formula C17H16F2O and a molecular weight of 274.31 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution, 1-(3,5-Difluorophenyl)-3-(3,4-dimethylphenyl)propan-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 274.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
